Abstract
One azotolane-containing acrylate monomer with a longer spacer and a non-azotolane crosslinker were synthesized. Crosslinked liquid crystal polymer (CLCP) films were obtained by thermal polymerization of the mixture of the monomer and the crosslinker with a molar ratio of 2:8. Thermodynamic and mesomorphic properties of the monomer, the crosslinker and the CLCP films were characterized by DSC and POM. The CLCP films showed a low glass transition temperature which ensured them to bend at room temperature upon visible light irradiation. Besides, the films have a faster bending speed compared with the previously-reported azotolane-containing CLCP films with a shorter spacer.
